Alright boys and grills I hope you're familiar with playing ADC in the jungle because that's what this is. You'll be playing Janna in the jungle to get that S+ because of the way the system grades your score and since nobody plays Janna jungle the game won't have anything to base your score off of so a terrible score like 12/7/12 will pull an S+ for you. I understand the pain of winning a game 0/6/30 and only ending up with an S-. The gameplay is simple, shield yourself to clear camps, recall frequently until level 6. After that gank lanes and shield like you would play Janna support if you haven't gotten enough items. Once you have items, shield yourself for health and bonus AD to capitalize on your attack speed. The trick is to play safe. Also I assume you're familiar with jungle, ADC, and Janna. You better know camp clear methods, good positioning and kiting for ADC, and general Janna strategies.
